It’s a special day, not a piece of paper.
And it can be special without spending 10k.
OP wants to now get married because she realises she is vulnerable. The ouece of paper is the important but to her.
This is the problem. People forget that above all, it's a legal piece of paper that gives some added protection to people in the ops position.
She could have had that a long time ago.
I dont buy it. She can afford not to work but more, in 13 years save up to protect herself.
I suspect, that the he doesnt earn a great deal. That would make sense to her believing they couldnt save to get married. It was cheaper for her to stay at home, because of child care. And these pre relationship assets are what provide the wealth. If so, chances are that that they werent impacted by her staying at home.
In all honesty, if my partner waant others about marriage, but then wanted to, years down the line when they realised my pre relationship assets wouldnt be shared if we split. I would be concerned too.
Also as it stands, op hasnt even seen the pre nup. She may be ok with it. She may more be. She may want to add something.
She may need to realise that a short marriage may end with her not being given access to them anyway.
Since she has hardly come back. Who knows.
I just dont think it's as simple and he is awful and she is at his mercy
